Vegetarian Onion Soup Recipe - Gourmet And Food

Before diving into the delicious world of vegetarian onion soup, consider what you can enjoy alongside it. This soup shines when paired with a variety of complementary dishes. A crisp side salad featuring a burst of seasonal vegetables, such as mixed greens and cherry tomatoes dressed with a light vinaigrette, can help balance the rich flavors of the soup. 
A slice of fresh, crusty bread, whether sourdough or a baguette, enhances the experience and captures the essence of the soup perfectly. If you enjoy cheese, a light assortment with soft cheeses like goat cheese and fresh herbs pairs exceptionally well. For something with a kick, bruschetta topped with tomatoes, garlic, and basil beautifully complements the warmth of the soup.

Ingredients

  • 4 tablespoons extra virgin olive oil
  • 1 cup Gruyère cheese, freshly grated optional; can substitute with vegan cheese
  • 1 tablespoon balsamic vinegar
  • 1/2 teaspoon smoked paprika
  • 3 pounds of yellow onions, peeled and cut into half-moon slices approximately 5 large ones
  • 1 1/2 teaspoons sea salt
  • 4 cloves garlic, finely minced
  • 8 cups vegetable broth
  • 1/2 cup robust red wine
  • 2 bay leaves
  • 1 tablespoon fresh thyme
  • 1/2 teaspoon freshly cracked black pepper
  • 2 tablespoons plant-based butter
  • 1 teaspoon sugar
  • 4 thick slices of crusty French bread

Instructions

Step 1: Gather Your Ingredients

  • Start by assembling all the ingredients. This not only makes your life easier but also keeps you organized. Once you have everything within arm’s reach, you’re setting yourself up for a smooth cooking session.

Step 2: Caramelize the Onions

  • In a large pot, heat the olive oil over medium heat. Add your sliced onions and sea salt. What will follow is a beautiful transformation. Stir occasionally, allowing the onions to soften and turn golden brown, about 30 to 40 minutes. Be patient; this step is golden!

Step 3: Add Garlic and Spices

  • Once your onions are perfectly caramelized, add the minced garlic and smoked paprika. This will add rich flavor. Stir and cook for an additional 2-3 minutes.

Step 4: Deglaze the Pot

  • Pour the red wine into the pot and scrape up any delicious bits stuck to the bottom. Let it simmer for 5 minutes until the wine reduces slightly.

Step 5: Add Broth and Herbs

  • Pour in the vegetable broth, add bay leaves, thyme, black pepper, and sugar. Bring the mixture to a boil, then reduce heat and let it simmer for about 20 minutes.

Step 6: Final Touches

  • Stir in the balsamic vinegar for an extra depth of flavor. If you're feeling cheesy, add the grated Gruyère cheese now or reserve it for serving.

Step 7: Prepare the Bread

  • While the soup simmers, toast thick slices of bread until golden. If desired, top with cheese and broil until bubbling and melty.

Step 8: Serve & Enjoy!

  • Ladle the soup into bowls, top with the cheesy bread, and dig in!

Notes

  • Take Your Time: Caramelization is key. The longer you cook the onions, the deeper the flavor.
  • Wine Selection: Use wine you would drink, as it directly impacts the soup's flavor.
  • Make Ahead: This soup allows for advance prep. The flavors deepen over time.
  • Storage: Keep leftovers in an airtight container in the fridge for up to three days.
  • Freezing: You can freeze this soup for up to a month. Thaw and reheat on the stove when you’re ready to enjoy!
